My invention relates to that class of mopsticlr heads which comprises ametallic body portion provided with a transverse groove along the endthereof and a clamping wire or bail adapted to fit within said grooveand hold the mop in place. The grooves in the cross heads have been asource oi considerable trouble, due to the fact that the flanges in themetal which form said grooves are apt to become bent out of shape. llthese flanges are bent inwardly or toward. each other a locking of theclamping wire will take place, and it" they are bent outwardly, there isdanger of the clamping wire slipping out of the groove and oil the head.

An object of the invention is to provide a construction ofinopstick'head in which great rigidity in the grooveoontaining portionthereof is attained, and in. which danger of bending the walls of thegroove is reduced to a minimum, V p

it. further object of the invention is to provide a novel constructionof mopsticlr headin which the parts thereotruay be assembled and held inoperating position without the use of rivets, tongues and otheranalogous securing devices.

-llther objects ot the invention will herein,- after appear and thenovel features thereof will be set forth in the claims.

My improvements have to do with the construction of the head 2. As.shown, it comprises a body portion 10 and channel-forming portion 11.The body portion 10 is preferably made from a blank 12 of sheet metalhaving a central longitudinally extending slit 13 therein, and anopening it. This blanlris stamped to produce the socket-forming portions15 and 16 and the outwardly extending flanges l? and 18. llt is thenbent along the line of the slot 13 to complete the formation of thesocket l, to provide two parallel strips or inatelialltl which lie inclose contact with each other and to provide the outwardly di rectedflanges 17and18. lrlleretofore, thehead would be completed by securingthe strips 19 together and utilizing the flanges 17 and 18 as the groovein which the clamping wire 5 fits, but according to my invention. llemploy an additional part 11, which l have termed a channeldormingportion. This is produced from a blank 20 by first curving the samelongitudinally to form the groove or channel 3 and afterwards bendingthe side portions of said blank back upon themselves to form the flanges21, 22, which are substantially parallel to the walls of the groove 3.These flanges, however, are slightly separated along their adjacentedges. The blank 20 is longer than the body portion 10 and at the endsthereof recesses 23 are formed. The extent of these recesses isincreased, after the parts have been assembled, by bending upwardly theedges thereof to form the retaining end flanges 2t. "llhese llangesengage the ends of the flanges ill, lb. The notched recesses formed bybending upwardly and inwardly thellanges 24 provide for the passage ofthe parallel portions of the clamping bail 5 at the ends of the crosshead and act as guides therelor. -llll'hen the blank 12 is folded toform the body portion of the head, stops 25 are formed in the lower partof the socket t by bending inwardly from opposite sides portions all themetal of blanln dill llll

lltlfl other.

In assembling the parts of the head 2, above described, the flatportions 19 of the blank 12, after the. latter has been folded uponitself, are held in contact with each other. The channel-forming part 11is then placed upon the body portion with the flanges 17 and 18 lyinginthe space between the flanges 21 and 22 and the upper side of thegroove 3. At this time the flanges 21 and22 are substantially parallelwith each They are afterwards turned inwardly, to their finalpositions,as shown in Figs. 2 and i, and the flanges 24 are turned up. The twoparts of the cross head are thus firmly and securely united and heldpermanently in place without the use of rivets, tongues or otheranalogous securing devices. And the cross head produced by thebody 10and channel-forming portions 11 is extremely rigid and unyieldingthroughout. The channel or groove 3 is formed by 'a' double thickness ofmetal so shaped as to prevent bending or curling from ordinary jars orblows, and in which spreading of the side walls of the groove iseffectually prevented. The'two parts of the head tend to reinforce eachother and produce a structurewhich is extremely strong and unyieldmg. I

I claim: v

1. A mop head comprising a body portion made up of parallel plateshaving opposed edges bent outwardly to form flanges, and

a member cooperating with said flanges having a groove or channelextending throughout the length thereof and formed with side flangeswhich embrace the flanges on the body portion. I p

2. A mop head made in two parts, one of which comprises a body memberprovided with outwardly extending flanges, and the other of whichcomprises a re-in'lorcing member provided with inwardly extendingflanges cooperating with the flanges on the first part to secure the twomembers together.

3. A mop head made in two parts, one of which comprises a body memberprovided with outwardly extending flanges, and the other of whichcomprises a re-intorcing member provided with a groove and inwardlyextending flanges cooperating with the flanges on the first part tosecure the two members together and is also provided with recesses atthe opposite ends of said groove.

4. A mop head made in two parts, one of which is provided with opposedoutwardly extending flanges, and the other of which is provided with agroove and inwardly extending flanges cooperating with the flanges onthe first part, and is also provided with recesses at the opposite endsof said groove and upturned flanges around said recesses.

5. A mop head comprising a body portion having parallel side membersprovided with outwardly extending flanges, and a member cooperating withsaid flanges having a groove formed therein throughout the lengththereof, and also having side flanges embracing the flanges of said bodymember, the said member being further provided with recesses at theopposite ends of said groove and with upturned flanges surrounding saidrecesses engaging the ends of the flanges of said body portion.

In witness whereof, I hereunto subscribe my signature.
